Question

基于标志Finesedequeue停止线程在下面的线程方法中我在停止按钮中做了一个循环（其目的是在填充名为_textFromFilesQueue的队列后停止此线程）并且主要问题在于我的形式冻结

这是我的代码：

线程方法：

 public static bool Finisedqueue ;
    public void  Read(string inputDirectoryPath)
    {

        try
        {
            Thread.CurrentThread.IsBackground = true;
            Finisedqueue = false;
            Console.WriteLine("thread 1 started");
            if (Form1.IsStarted)
            {
                Thread.Sleep(3000);
                var dir = new DirectoryInfo(inputDirectoryPath);
                FileInfo[] f = dir.GetFiles("*.txt");
                if (f.Length > 0)
                {
                    Console.WriteLine("{0} directory contains {1} Files",inputDirectoryPath,f.Length);
                    int counter = 0;
                    foreach (System.IO.FileInfo fi in f)
                    {   

                        counter++;
                        var filePath = Path.Combine(fi.DirectoryName, fi.Name);
                        string textFromFile = File.ReadAllText(filePath);
                        _textFromFilesQueue.Enqueue(textFromFile);
                        Console.WriteLine("The text inside file number {0} is : {1}",counter,textFromFile);
                       fi.Delete();
                        Console.WriteLine("deleting file number {0} from input folder",counter);


                    }
                    Finisedqueue = true;
                    Console.WriteLine("finished Deleting files");
                }

                else
                {
                    Console.WriteLine("{0} Has no files inside it ",inputDirectoryPath);
                }
            }

        }
        catch (Exception excep)
        {
            Console.WriteLine("An error occurred: '{0}'", excep);
            throw(excep); 

        }
    }

停止按钮单击：

        private void stop_Click(object sender, EventArgs e)
    {

        while (!Thread1.Finisedqueue)
        {
            Console.WriteLine("Queue from First Thread is still Enqueuing data");
        }
        Thread1Timer.Dispose();
        button3.Enabled = true;
        textBox3.Enabled = true;



    }

忙碌时等待睡觉是个好主意，这样你就可以让其他线程有机会执行。

您还可以查看Task类 https://msdn.microsoft.com/en-us/library/system.threading.tasks.task(v=vs.110).aspx这对于诸如文件IO之类的异步操作很有用，并且可以使用内置的while (!Thread1.Finisedqueue) { Thread.Sleep(100); Console.WriteLine("Queue from First Thread is still Enqueuing data"); }功能来等待。

async/await

填充队列后停止线程工作
